METAL-FRAME AND CONCRETE SIDEWALK, 8w.

Specification of Letters Patent.

Patented July 14, 1914.

Application filed May 8, 1913. Serial No. 766,424.

To all whom it may concern Be it known that I, HARRY F. BAYLEY, acitizen of the United States, and resident of Milwaukee, in the countyof Milwaukee and State of Wisconsin, have invented cer tain new anduseful Improvements in Metal- Frame and Concrete Sidewalks, 850.; and Ido hereby declare that the following is a full, clear, and exactdescription thereof.

My invention consists in what is herein particularly set forth withreference to the accompanying drawings and pointed out in the claims ofthis specification, its object being to facilitate setting ofglass-lights in metal frame and concrete sikewalks, vaultcovers and thelike, as well as to compensate for contraction and expansion of thelights, and also to make 1t possible to replace a defective or fracturedlight without disturbing the adjacent concrete.

Figure 1 of the drawings represents a plan view of a fragment of a metalframeand concrete sidewalk having glass-lights set therein in accordancewith my invention; Fig. 2, a sectional View indicated by line 2+2 inFig. 1, and Fig. 3, a plan view of a light holder inverted.

Referring by numerals to the drawings, 1 indicates each of a series ofright-angle irons suitably spaced apart and having the vertical websthereof notched at predetermined intervals for the engagement oftrough-like irons 5, the intermatching irons serving to form a frame.Supported on the frame, on edges of the irons 5 to abut one another andthe irons 4, are holders 6 for glass lights 7, and concrete 8 is set insaid irons 5 and between the light-holders flush with the upper edges ofsaid holders and the lights therein.

Each light-holder is a casting herein shown in the form of a rectangularshell of suitable depth having flanges inwardly projecting from allwalls thereof at the bottom to form a horizontal seat 9 for the light 7laid therein, and horizontal bottom flanges 10 extend outwardly from twoopposite walls of said casting toabut a like flange of a similar castingand the irons 4, whereby spaces are provided for concrete filling.However it is within the scope of my invention, as herein claimed, toshape the shell of each holder for other than a rectangular form oflight. To prevent lateral play of the light-holders on the irons 5, ofthe aforesaid frame,

each of said hold= ers is provided with depending lugs 11 that abut saidirons.

Each of the glass-lights 7 is of less area throughout than the spacewithin the walls of its holder and being centered on its seat,

a filling of elastic plastic composition 12 other than the concreteaforesaid is poured, in a melted state, between the light and saidwalls, the thickness of said light being equal to the depth of itsholder above the seat therein. The composition, when set, compensatesfor expansion and contraction of the light and thus the liability ofsaid light to fracture is obviated, this being an important feature ofmy invention. In case the light should become fractured from any causeor be found defective, it and the elastic filling material may bereadily removed from the holder, without disturbing the adjacentconcrete, and a new light and filling substituted.

I claim:

1. A sidewalk, vault-cover or the like comprising a metal frame,independent holders supported on the frame and each consisting of acasting in the form of a shell inwardly flanged at the bottom to form ahorizontal seat and having outer bottom flanges extending in oppositedirections to abut elements of said frame and like flanges of otherholders, concrete in which the holders are embedded, glass-lights ofless area throughout than the interiors of said holders in which theyare seated, and elastic composition filling other than the concreteaforesaid surrounding each light in its holder.

2. A sidewalk, vault-cover or the like comprising a metal frame, holderssupported on the frame and each consisting of a casting in the form of ashell provided with depending lugs that abut members of said frame, eachholder being inwardly flanged at the bottom to form a seat and havingouter bottom flanges extending in opposite directions, concrete in whichthe holders are embedded, glass-lights of less area than the interiorsof said holders in which they are seated, and elastic compositionfilling surrounding each light in its holder.

3. As an article of manufacture, a glass light holder for metal frameandconcrete sidewalks, vault-covers and the like, the same consisting ofa casting in the form of a shell inwardly flanged at the bottom to forma horizontal seat and having outer horizontal bottom flangesv extendingin opposite directions, the interior of the holder being of gneater areathroughout than the.

light to be secured therein, whereby an elastic composition filling mayhe utilized on said seat to fill the space above the same between saidlight and holder;

4:. As an article of manufacture,a glasslight holder for metal frame andconcrete sidi Well s, make ver an th l the same consisting of a castingin theform ,of a shell pr vide wi d pe di g l gs, a whi h is inwa dlyflang d at he bot om greater area than the light to be secured therein.

In testimony that I claim the foregoing I have hereunto set my hand atMilwaukee, 20

in the county of Milwaukee and State of Wisconsin, in the presence oftwo witnesses.
